Abstract
Perkembangan teknologi untuk memenuhi kebutuhan manusia tidak mungkin bisa jalan ditempat. Salah satunya teknologi seluler yang sedang dikembangkan manusia adalah 5G. Teknologi ini menawarkan efisiensi bandwidth yang bagus, data rate yang tinggi, serta latensi yang tinggi. Tantangan infrastruktur pembuatan jaringan tersebut sangatlah rumit daripada generasi sebelumnya. Penggunaan millimeter wave sebagai media transmisinya memiliki kelemahan karena sangat rentan terpengaruh oleh obstacle lingkungan. Kemudian karena dibutuhkan data rate yang tinggi maka diperlukan banyak antena atau biasa disebut Massive MIMO.
Pada tugas akhir ini dilakukan peneitian mengenai antena Massive MIMO Microstrip crosspolar (Dual Polarization) untuk memenuhi kebutuhan pembangunan infratruktur tersebut. Kelebihan crosspolar disini adalah untuk meminimalisir efek dari millimeter wave yang mudah terpengaruh oleh obstacle lingkungan. Desain antena tersebut ada dua, yang pertama desain antena satu layer dengan pencatu probe feeding. Sedangkan yang kedua, desain antenanya menggunakan 3 layer substrate dengan teknik pencatuan aperture coupling. Kedua antena tersebut memiliki dua polarisasi, baik vertikal maupun horizontal..
Antena tersebut bekerja diantara rentang frekuensi 5-6 GHz. Kemudian, kedua antena tersebut memiliki nilai isolasi yang baik pada setiap elemen singlenya. Untuk penyususan arraynya, antena probe feeding disusun dengan jarak antar elemen λ_g/2 sedangkan antena stacked disusun berjejer langsung. Keduanya disusun secara array linier 1x3. Keduanya memiliki nilai isolasi yang baik dibawah – 20 dB

The development of technology to fulfill human needs. One of the cellular technologies being developed by humans is 5G. This technology offers good bandwidth efficiency, high data rates, and high latency. The challenge of making the network infrastructure is very complicated than the previous generation. The use of millimeter wave as a transmission medium has a weakness because it is very susceptible to being affected by the obstacle environment. Then because a high data rate is needed, a lot of antennas are needed or commonly called Massive MIMO.
In this final assignment, a study of a Massive MIMO crosspolar Microstrip (Dual Polarization) was conducted to meet the infrastructure development needs of the infrastructure. Crosspolar's advantage here is to minimize the effects of millimeter waves that are easily affected by the obstacle environment. The antenna design is twofold, the first one layer antenna design with feeding probe feeder. Whereas the second, the antenna design uses 3 substrate layers with the technique of aperture coupling. Both antennas have two polarization, both vertical and horizontal.
The antenna works between the 5-6 GHz Frequency range. Then, the two antennas have good insulation values for each single element. For the array array, antenna feeding probes are arranged with distances between elements λ_g / 2 while stacked antennas are arranged in direct line. Both are arranged in a 1x3 linear array. Both have isolation values that are well below - 20 dB.
